Vibration and rotation force: Dental scalers typically use vibration or rotation to clean teeth surfaces and gum pockets. This force effectively removes dental plaque and tartar, making the mouth cleaner.

Water pressure: Most modern dental scalers are equipped with adjustable water pressure functions, allowing users to adjust the pressure according to their needs.                                           

Charging and durability: Dental scalers are typically rechargeable, using lithium batteries or other charging technologies.                   

Waterproof design: Dental scalers generally have a waterproof design to ensure that the circuits or motors are not damaged by water during use
